IMPROVEMENT IN WINDOW-SASHES.

Specification forming part of Letters Patent No'. 131,662, dated September 24, 1872.

To all whom it may concern: I

Be it known that I, DANIEL H. CARPENTER,

, of Hartford, in the county of Hartford ,and

being had to the annexed drawing making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawing is arepresentation of a front view; Fig. 2 is a horizontal section, and Fig. 3- is a vertical section, of my invention. I

This invention window-sashes for the windows of fire-proof buildings; and the novelty consists in striking up, by means of dies or bending-machines,

the sides and bottom of a sash, each froma single stripof sheet metal, to the form hereinafter described; the object being to adapt the sash to the reception of the glass, and to its position with respect to the side, top, and bottom ribs or slats of the frame. 1

The object of making the sashes of metal is to adaptthem to use in connection with metallic window-frames and blinds .or shutters so as to render. the window wholly fireproof. I use sheet metal in the construction of said sashes for the reason. that the sashes made therefrom will be as .light and easily handled as those made of Wood, and also because the sheet metal may be more easily struckup to any desired form, with corrugationsjand moldings corresponding to the style of architecture of the building, than sashes made of cast metal.

As my invention relates principally to the form to which the sides and bottoms of the sashes are struck upI will proceed to describe the same.

has relation to sheet-metal In the accompanying drawing, A represents a metallic window-frame, having ribs B B to guide the sashes and to hold them'in place. A represents the window-sashes, of which (1 are the sides and d the bottom strips. Each of said strips is formed from a plate of sheet metal, of proper length and width, which is struck up in a die, or by a bending machine,

.to a form approximating in its transverse section the letter M. These strips are afterward secured together at their ends, their edges lying toward the outside. The sides of. the

strips d embrace the side ribs or guides B, while the sides of the strip 01 may embrace the bottom rib of the frame A; but in some cases the sash may be so arranged as not to be intended to fall to the bottom of the frame.

The channels-m in said strips produce a con= V tinuous groove or recess around the sides and bottom of the sash, into which the glass fits. The top part of the sash is composed of two strips, a, with an opening between them to let the glass pass through. D designates a packing of India rubber, lead, or other material, which, being cut in narrow strips, is placed over the edges of the glass, or inserted in the grooves m. This packing is used for the purposes of securing the glass rigidly and'protecting it from injury.

What I claim as my invention, and desire to secure by Letters Patent, is

A window-sash constructed of sheet-iron, with the parts 11 d struck up in a die to the form of a letter M, and adapted to use substantially as specified.

In-testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
